An old binder in Tulsa handed me a bone folder and it ruined my plastic one for good
Spent two years creasing signatures with a cheap plastic folder until this guy at a supply swap let me try his bone one for a single book, and now I can't stand the sound or the rounded edges of plastic, so I guess I owe him a thank you for costing me $22.
Totally thought the bone folder hype was overblown until a friend let me borrow hers last month. Now my cheap plastic one just sits in a drawer collecting dust.
